i am jealous that you are in uci height category 3 and have got 14cm to play with for the aero extension rise. I was in the market for some aero extensions for my TT:ONE i had a look at the TRONE cockpit and the rise looks to be greater than the 12cm i am allowed in my UCI height category (even with 0 degree angle washers). And for that matter, most of the wattshop/fast TT copies on Ali look to cater for the triathlon crowd, since most look to be greater than 14cm rise. In any case I don't want to spend $600+ so also looked at aliexpress for cheaper options. I ended up ordering these last week in size small to (hopefully) sit within the 830mm limit from centre of BB to tip of extensions:

and the rise doesn't look to be too great, so (again hopefully) i can adjust so for around a 12cm rise from armrest to tip.

Also ordered this adaptor plate, the seller told me it should fit the monoriser on my TT:ONE, if not will drill out correct hole spacing.

Haha yes, one good thing with being over 190cm tall in cycling! Otherwise my height just makes me rather like a sail in the wind...

Please tell me how this went with the Winow extensions! I've looked at them as well. And the adaptor plate is a good shout, been looking for something like that.

They are available to buy.

Wow, thanks! Amazing how when I inquired on 21th May, I got the response "Sorry, we do not sell this item separately.". I will be in contact with them as well.

Does anybody know who makes the TR:One aero extensions and if they are available on Ali? The dimensions and specs look excellent and, unlike Winow offerings, their length is customizable. Quick Pro USA replied to me that they can't be sold separately, while Panda Podium has yet to confirm directly from Quick.

Alternatively, if anyone knows of similar extension systems, please share!

I bought the Mondince FM316 last fall and I've been very impressed with it. The geometry is spot on for me, I love the longer reach and steeper seattube. I now have it set up with a slammed 130mm -17 stem to get the reach even longer, and I use the Ascent Aeroo Road handlebars to get a really nice and comfortable aero position. The back end seems more comfortable than the Tideace Noah that I had before. My only issue honestly is the tyre clearance – I've been using Tufo Thundero 48mm's with 25IW wheels, and I don't really feel comfortable going any wider on the back. Maybe 50mm's could work, but I dunno. I don't think I would be comfortable using 2.1inch TB's on this bike. I don't think I _need_ any wider than 48mm, but having that option for some terrain would be great!

I have a Quick Pro ER:one and I've thought about switching to a separate stem + handlebar combo (need to update my 34cm Zephyr handlebars in any case). Does anyone know if a normal FSA ACR headset would work with the bike, as it should be 52mm?

Hi, congratulations on the bike, also built with top-notch components. As for the crankset, did you use a standard SRAM or a longer Wide axle? Total weight and size of the bike?

Thank you! I just weighed it at just under 8.5kg with pedals and bottle cages, the size is L. It is a Dub Wide crankset.

Here it is built up, the LBS was super fast. No problems with the BB, paint, brake mounts etc. Clearance with 48mm Thunderos on 25IW rims (wam just under 50mm) is really great. I will ride it on tarmac this afternoon and tweak the fit a bit. Really loving how this looks, the back end and top tube is quite slender and I really like how that pairs with the bigger rubber. The Tideace Noah I had previously looked much more porky.

I just got a message from Mondince that my frame is now shipped. 12 days from ordering, not bad! Now it'll probably take a couple of weeks for it to arrive here to Finland.
